Yesterday, light soybean rust infection was observed in Noxubee County, MS in soybean plants beyond the R5.5 growth stage. The specific information in this blog post should serve as an update to the soybean rust disease situation as well as including some general guidelines with regards to potential disease management scenarios.

We saw a surge in RBSB numbers a few weeks ago into March planted soybeans that were approaching R6 growth stage but since then populations have moderated. Just in the last few days we are now seeing another big surge moving into

Increased reports of disease in the corn crop in MS have been made over the past week. Normally, as corn matures, the incidence and severity of corn diseases observed with increase. Presently, common rust, Diplodia leaf streak, northern corn leaf blight, and southern rust can all be observed in our corn production system; however, southern rust has only been observed on an extremely limited number of acres to this point in the season.

Diagnosing common and southern rust in the field can oftentimes be difficult. Subtle differences between the two diseases can occur at different parts of the growing season as well as sections of the crop canopy.

Mississippi State University will be hosting 4 scout schools this year. We have transitioned over the years to make these trainings much more diverse than insect pest alone. This year we will be including insects, disease, fertility, and herbicide symptomology. There

This is a video showing the methods used to determine the vegetative growth stages of corn or sorghum in the field. Further information can be found in the accompanying Mississippi Crop Situation blog article.

Vegetative growth stages of corn or sorghum are determined by counting the number of fully emerged leaves with leaf collars present. This methodology can be used to anticipate growth and determine appropriate timing of many management decisions, including herbicide application, sidedress fertilizer, etc….

Limited wheat acres in MS have meant for a fairly quiet winter. However, the observation of wheat diseases has increased over the past several weeks with the major questions coming from either vernalization issues (lack of chilling hours) or leaf rust.

Target spot was one of the main diseases that occurred during 2016. Normally a disease of little consequence in soybean as well as cotton, severe target spot outbreaks were observed in both crops. Making decisions regarding the occurrence of target spot during 2016 are difficult since the environment during key plant growth stages was the most important ingredient for the occurrence of target spot last season.

We have been working on an insect control guide app for a couple years and are proud to say it is now available in the app store for iPhones. Shortly we will be releasing a version for Android users as

In 2017, the need to maximize thrips control to avoid foliar applications will be more important than ever. With the introduction and anticipation of numerous acres with the new herbicide traits resistant to Dicamba, there will be NO INSECTICIDE tank

Foliar diseases continue to be observed throughout the MS soybean production system. Cercospora blight, frogeye leaf spot and target spot have been commonly observed. Soybean rust continues to be observed at low levels in areas where the disease has occurred following the rainfall received over the last month.

Over the last few weeks we have been getting more and more calls about redbanded stink bug in soybeans. Redbanded stink bugs (RBSB) are voracious seed feeders, infest fields later, and are more difficult to control than greens, southern greens,

Bollworm: We have had numerous reports of bollworm (soybean podworm corn earworm) moths being flushed and small larvae in cotton and soybeans over the last couple weeks. This past week seemed to be the turning point in soybean. Nearly anyone with

Save for the appearance of a few common foliar diseases, the soybean disease situation remains fairly quiet. Septoria brown spot appears to be the most commonly occurring foliar disease. Scout fields for the presence of nematodes as well as stem diseases now to aid in next season’s decisions.

To date, disease issues in the MS corn crop have remained somewhat quiet. Common rust has been the most prevalent disease as a result of wetter and cooler temperatures until the past 7 to 10 days. As of this morning (6/18/2016), southern rust has not been detected in MS.

Spider mites have been becoming more widespread over the last two weeks. Currently we have quite a few acres requiring treatment for spider mites and several that have already received an application. The hot dry weather we have been dealing with

Included in this blog post are a rice disease calendar. Information presented in the calendar deals with the most commonly observed rice diseases throughout the MS rice production area. In general, the occurrence of diseases on rice will depend on the planting date, general field history as related to previous crop, and the environmental conditions throughout the season.

On Tuesday, May 24, 2016, soybean rust was detected on kudzu in Amite, Pike and Wilkinson counties in southwest MS. The observations of soybean rust yesterday mark the earliest appearance of the disease by a little more than 6 weeks as compared to the past. No specific management practices are suggested at this time.

Included in this blog post are updated disease calendars for MG IV and MG V soybean to aid in scouting plant diseases. Keep in mind that several variables can impact the time of year when specific diseases are observed. Planting date, variety susceptibility, number of years a particular field has been in soybean, and prevailing environment can all play a role in when a disease is observed.

Increased observations of foliar wheat diseases have occurred over the past two weeks. Leaf rust, stripe rust and Septoria leaf blotch have been commonly observed throughout the state. In addition, with the current environmental conditions (humidity, rainfall) and the general growth stages observed, the potential for Fusarium head blight (scab) may be similar to as occurred during the 2015 season.
